Question - How do one send data between two in +CWMODE=3. Can it be selected to +CIPSENDEX over either STATION connection or AP SERVER connection

Can +CIPSENDEX data from ESP_A to ESP_B, but ESP_B can not send data back as I think it creates UDP socket for its own AP

- Example of fail below.

(ESP_B connect to ESP_A AP)

ESP_A
+CWMODE_DEF=3
+CWSAP_DEF="A_SSID","A_PW",6,4 (ESP_B successful connect and get IP 192.168.4.2)
+CIMUX=0
+CIPSTART="UDP","192.168.4.2",5001,5001,0 (Connect OK)
+CIPSENDEX=5 >12345\0 (SEND OK and ESP_B receive data)

ESP_A
+CWMODE_DEF=3
+CWJAP_DEF="A_SSID","A_PW" (ESP_B succesfull connect and get IP 192.168.4.2)
+CIMUX=0
+CIPSTART="UDP","192.168.4.1",5001,5001,0 (Connect OK)
+CIPSENDEX=5 >12345\0 (SEND FAIL)

Please assist
